Description

Technical Field

[0001] This utility model relates to the field of hand treatment device technology, and in particular to a hand visualization fixation device. Background Technology

[0002] The human hand has a certain degree of dexterity and tactile sensation. When performing visual interventional treatment on the hand, a single fixed assistive device such as an ordinary bed sheet or soft pillow is usually used to restrict the hand. However, this method cannot effectively restrict the finger area, affecting the safety and accuracy of the treatment and making the patient feel uncomfortable. Utility Model Content

[0003] The purpose of this utility model is to provide a hand visualization fixation device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a hand visualization fixing device, comprising: a fixing plate with a hand support plate mounted on the top; a first finger plate rotatably mounted on the outer periphery of one end of the hand support plate, the fixing plate being equipped with a first angle limiting member for limiting the rotation of the first finger plate relative to the hand support plate; a second finger plate rotatably mounted on the end of the first finger plate away from the hand support plate; a third finger plate rotatably mounted on the end of the second finger plate away from the first finger plate, and second angle limiting members for limiting relative rotation are installed between the first finger plate and the second finger plate and between the second finger plate and the third finger plate, and the hand support plate, the first finger plate, the second finger plate and the third finger plate are each provided with limiting straps for limiting the arm and fingers.

[0005] This technical solution has at least the following beneficial effects: The hand is placed on a hand support board, with fingers correspondingly placed on the first, second, and third finger plates, and then restrained by a limiting band. The thumb and toe are placed on the part without the third finger plate. By adjusting the angle of the first finger plate relative to the hand support board and fixing it with a first angle limiting component, adjusting the angle of the second finger plate relative to the first finger plate and fixing it with a corresponding second angle limiting component, and then adjusting the angle of the third finger plate relative to the second finger plate and fixing it with a corresponding second angle limiting component, the fingers can thus form the required specific position and posture, meeting various surgical treatment requirements, ensuring the safety and accuracy of treatment, improving the patient experience, achieving the standard position for hand ultrasound visualization guidance, and assisting in the surgical process, facilitating surgical operation, and improving surgical efficiency and success rate.

[0006] As a further improvement to the above technical solution, the first angle limiting component includes a first rod rotatably disposed on the fixed plate and a second rod sleeved on the first rod. The end of the second rod away from the first rod is rotatably mounted on the bottom of the first finger plate. The second rod is equipped with a fixing component for limiting the sliding of the first rod relative to the second rod. When it is necessary to adjust the angle of the first finger plate, the first finger plate is swung, causing the first rod and the second rod to slide relative to each other to achieve extension and retraction, and is fixed by the fixing component. This allows the first finger plate to be restricted to the required swing angle position relative to the hand support plate, facilitating a wide range of angle adjustments.

[0007] As a further improvement to the above technical solution, the fixing component is a sleeve threaded onto the bottom end of the second rod. The bottom end of the second rod is circumferentially provided with multiple elastic arc plates. The inner side of the sleeve is provided with a conical surface that abuts against the elastic arc plates and clamps the multiple elastic arc plates onto the first rod. By rotating the sleeve, the sliding between the first and second rods can be easily restricted and released, facilitating the adjustment of the angle of the first finger plate.

[0008] As a further improvement to the above technical solution, the second finger plate is provided with a plurality of first positioning holes along the rotation center relative to the first finger plate, and a second positioning hole is provided on the side of the first finger plate. The second angle limiting member is a positioning pin that is sequentially inserted into the first positioning hole and the second positioning hole. When the second finger plate is swung relative to the first finger plate to the desired angle position, the positioning pin is inserted into the first positioning hole opposite to the second positioning hole and passes through the second positioning hole, thereby restricting the rotation of the second finger plate relative to the first finger plate and fixing the angle position of the second finger plate.

[0009] As a further improvement to the above technical solution, a rotating shaft is provided on both sides of one end of the second finger plate, and a sliding groove is provided on both sides of the first finger plate for the rotating shaft to be inserted and rotated. Multiple second positioning holes are arranged side-by-side within the sliding groove. The rotating shaft can also slide within the sliding groove, thereby adjusting the sliding position of the second finger plate relative to the first finger plate. The rotation angle and sliding position are then fixed by inserting into the corresponding second positioning holes, thus adapting to patients with different finger joint lengths and improving the device's adaptability.

[0010] As a further improvement to the above technical solution, the positioning pin includes two pin ends, which can improve the stability of the connection.

[0011] As a further improvement to the above technical solution, the second finger plate is provided with a clearance slot for the first finger plate to swing. This improves the flexibility of relative rotation between the first and second finger plates.

[0012] As a further improvement to the above technical solution, either the first finger plate has seven fingers and the two second finger plates on both sides do not have the third finger plate, or the first finger plate has five fingers and the one second finger plate on one side does not have the third finger plate. The combination of seven first finger plates can accommodate both left-handed and right-handed use simultaneously, further improving the device's adaptability.

[0013] As a further improvement to the above technical solution, an adjustable-height support frame is installed at the bottom of the fixing plate to facilitate support for the patient's hand.

[0014] As a further improvement to the above technical solution, the bottom of the support frame is equipped with braked rollers, which facilitates moving the device to a suitable position. Attached Figure Description

[0026] Reference Figure 1-5 The hand visualization and fixing device includes a fixing plate 100 and a hand support plate 110. Two support blocks are installed on the top of the fixing plate 100. The hand support plate 110 is detachably installed on the top of the support blocks by screws, so that the hand support plate 110 is suspended above the fixing plate 100. One end of the hand support plate 110 is fan-shaped, and seven first finger plates 210 are distributed around the outer periphery of the fan shape. One end of the first finger plates 210 is rotatably installed at the edge of the fan shape at the end of the hand support plate 110.

[0027] A first angle limiting member 300 is installed on the top of the fixed plate 100. The first angle limiting member 300 includes a first rod 310, a second rod 320, and a fixing member. The first rod 310 is a solid rod, and the second rod 320 is a hollow rod. One end of the first rod 310 is rotatably mounted on the top of the fixed plate 100, and the other end of the first rod 310 is slidably sleeved on one end of the second rod 320. The end of the second rod 320 away from the end sleeved with the first rod 310 is rotatably mounted on the bottom of the first finger plate 210 away from the end of the hand support plate 110. When the first rod 310 and the second rod 320 slide relative to each other, the first finger plate 210 can swing relative to the hand support plate 110, thereby adjusting the angle position of the first finger plate 210. When the first finger plate 210 is in a horizontal state, both the first rod 310 and the second rod 320 are in a vertical state.

[0028] The fastener includes a sleeve 330 and an elastic arc plate 340. The sleeve 330 is fitted onto the outside of the second rod 320 and is threadedly connected to the end of the second rod 320 away from the first finger plate 210. The thickness of the elastic arc plate 340 is adapted to the curvature and thickness of the second rod 320. Multiple elastic arc plates 340 are provided, and they are evenly arranged around the end face of the second rod 320 away from the first finger plate 210. A conical surface 331 is provided on the inner side of one end of the sleeve 330. The conical surface 331 is located on the outside of the first rod 310.

[0029] The conical surface 331 abuts against the end of the elastic arc plate 340 away from the second rod 320. Multiple elastic arc plates 340 clamp the first rod 310, thus fixing the first rod 310 and the second rod 320 in a relatively fixed state. When the angle of the first finger plate 210 needs adjustment, the sleeve 330 can be rotated forward, causing it to move axially relative to the second rod 320. The conical surface 331 disengages from the elastic arc plate 340, allowing the elastic arc plate 340 to no longer clamp the first rod 310, and the first rod 310 and the second rod 320 to slide relative to each other, thereby adjusting the angle of the first finger plate 210. After adjustment, the sleeve 330 is rotated in the opposite direction, causing the conical surface 331 to abut against the end of the elastic arc plate 340 away from the second rod 320. Multiple elastic arc plates 340 clamp the first rod 310, fixing the position between the first rod 310 and the second rod 320, thus fixing the adjusted angle of the first finger plate 210.

[0030] In other embodiments, the first angle limiting member 300 may also be a threaded rod threadedly installed on the handle plate 110. The threaded rod is threaded through one side of the handle plate 110 and abuts against the side wall of the first finger plate 210, thereby using the friction between the threaded rod and the first finger plate 210 to stabilize the angle position of the first finger plate 210.

[0031] In other embodiments, the fastener may also be a pin passing through the second rod 320, and the first rod 310 has a plurality of fixing holes arranged side by side along its length for the pin to be inserted. By passing the pin through the second rod 320 and inserting it into the corresponding fixing holes, the relative positions of the first rod 310 and the second rod 320 can be fixed, thereby fixing the angular position of the first finger plate 210.

[0032] A second finger plate 220 is installed at the end of the first finger plate 210 away from the handle plate 110. A second angle limiting member 400, which is a positioning pin, is provided between the first finger plate 210 and the second finger plate 220. Both sides of one end of the second finger plate 220 are provided with discs, and a rotating shaft 500 is provided on the opposite side of the two discs. Multiple first positioning holes 410 are provided around the rotation center line of the rotating shaft 500 of the discs. The first finger plate 210 has grooves 510 along its length on both sides. The rotating shafts 500 on both sides of the second finger plate 220 are respectively embedded in the corresponding grooves 510. The width of the grooves 510 matches the diameter of the rotating shafts 500, allowing the second finger plate 220 to rotate relative to the first finger plate 210, with the rotation center line being the rotation center line of the rotating shafts 500. Simultaneously, the rotating shafts 500 can also slide within the grooves 510 along the length of the first finger plate 210, thus allowing one end of the second finger plate 220 to move relative to the first finger plate 210. Therefore, rotation and movement of the second finger plate 220 relative to the first finger plate 210 can be achieved.

[0033] Multiple second positioning holes 420 are arranged side-by-side along the length of the first finger plate 210 on the bottom wall of the slide groove 510. The distance between two adjacent second positioning holes 420 is the same as the distance between two first positioning holes 410 of the same diameter on the disc, or the distance between two adjacent second positioning holes 420 is half the distance between two first positioning holes 410 of the same diameter on the disc. The positioning pin is U-shaped, and both ends of the positioning pin are pin ends, giving the positioning pin two pin ends. The two pin ends of the positioning pin pass through two first positioning holes 410 of the same diameter and are embedded in the corresponding two second positioning holes 420, thereby restricting the rotation and sliding of the second finger plate 220 relative to the first finger plate 210, thus stabilizing the relative angular position and relative displacement position between the second finger plate 220 and the first finger plate 210.

[0034] The second finger plate 220 has a clearance slot 600 at the middle of one end near the hand support plate 110. The clearance slot 600 allows the end of the first finger plate 210 away from the hand support plate 110 to be inserted and swing, thereby improving the flexibility and operability of position adjustment between the second finger plate 220 and the first finger plate 210. The first finger plate 210 can be set to a size shorter than the length of the first phalanx of a standard hand.

[0035] A third finger plate 230 is mounted on the end of the second finger plate 220 away from the first finger plate 210. A second angle limiting member 400, which is a positioning pin, is also provided between the third finger plate 230 and the second finger plate 220. Both sides of one end of the third finger plate 230 are provided with discs, and a rotating shaft 500 is provided on the opposite side of each disc. Multiple first positioning holes 410 are provided around the rotation center line of the rotating shaft 500 on each disc. Both sides of the second finger plate 220 have sliding grooves 510 along their length. The rotating shafts 500 on both sides of the third finger plate 230 are respectively embedded in the sliding grooves 510 on the corresponding sides of the second finger plate 220. The width of the sliding grooves 510 is adapted to the diameter of the rotating shafts 500, allowing the third finger plate 230 to rotate relative to the second finger plate 220, with the rotation center line being the rotation center line of the rotating shaft 500. Meanwhile, the rotating shaft 500 can also slide along the length of the second finger plate 220 within the slide groove 510, thereby allowing one end of the third finger plate 230 to move relative to the second finger plate 220. Therefore, rotation and movement of the third finger plate 230 relative to the second finger plate 220 can be achieved.

[0036] Multiple second positioning holes 420 are arranged side-by-side along the length of the second finger plate 220 on the bottom wall of the slide groove 510. The distance between two adjacent second positioning holes 420 is the same as the distance between two first positioning holes 410 of the same diameter on the disc, or the distance between two adjacent second positioning holes 420 is half the distance between two first positioning holes 410 of the same diameter on the disc. The positioning pin is U-shaped, and both ends of the positioning pin are pin ends, giving the positioning pin two pin ends. The two pin ends of the positioning pin are respectively inserted into the two first positioning holes 410 of the same diameter and embedded in the corresponding two second positioning holes 420, thereby restricting the rotation and sliding of the third finger plate 230 relative to the second finger plate 220, thus stabilizing the relative angular position and relative displacement position between the third finger plate 230 and the second finger plate 220.

[0037] The third finger plate 230 has a clearance slot 600 at the middle of its end near the second finger plate 220. The clearance slot 600 allows the end of the second finger plate 220 furthest from the first finger plate 210 to be inserted and swung, thereby improving the flexibility and operability of position adjustment between the third finger plate 230 and the second finger plate 220. It is understood that the structure of the third finger plate 230 is the same as that of the second finger plate 220, only differing in length according to requirements.

[0038] In this embodiment, the number of second finger plates 220 corresponds to the number of first finger plates 210, and there are five third finger plates 230, which are respectively connected to the five second finger plates 220 located in the middle. It can be understood that the two second finger plates 220 located on both sides are not connected to the third finger plates 230.

[0039] When the first finger plates 210 are described sequentially from one end to the other, if the first finger plate 210 corresponds to restricting the thumb of the palm, then the second finger plate 210 is empty; the third finger plate 210 corresponds to restricting the index finger; the fourth finger plate 210 corresponds to restricting the middle finger; the fifth finger plate 210 corresponds to restricting the ring finger; the sixth finger plate 210 corresponds to restricting the little finger; and the seventh finger plate 210 is empty. At this time, the first, third, fourth, fifth, and sixth finger plates 210 can correspond to the distribution posture of each finger in the human hand (such as the front of the left hand and the back of the right hand).

[0040] When the first finger plate 210 is empty, the second finger plate 210 restricts the little finger, the third finger plate 210 restricts the ring finger, the fourth finger plate 210 restricts the middle finger, the fifth finger plate 210 restricts the index finger, the sixth finger plate 210 is empty, and the seventh finger plate 210 restricts the thumb. At this time, the second, third, fourth, fifth, and seventh finger plates 210 can also correspond to the distribution posture of each finger in the human hand (such as the back of the left hand and the front of the right hand).

[0041] Therefore, the finger-restricting assembly consisting of seven first finger plates 210, seven second finger plates 220 and five third finger plates 230 can be adapted to both left and right hands and the front and back of the palm, and the finger restriction posture can adapt to the position of each finger on the palm, making the finger restriction process more comfortable and improving the patient's body sensation.

[0042] Each of the first finger plate 210, the second finger plate 220, and the third finger plate 230 is equipped with a limiting strap 700, which can be a binding rope or Velcro. The arm is placed on the hand support plate 110, and each finger is correspondingly restrained on the first finger plate 210 and its connected second finger plate 220 and / or third finger plate 230, further restricted by the limiting straps 700. This allows for the limitation of the finger's position and posture, facilitating surgical treatment of the fingers or palm.

[0043] In other embodiments, a hand support plate 110 may also have only five first finger plates 210. In this case, only four third finger plates 230 are provided, and the four third finger plates 230 are respectively connected to four adjacent second finger plates 220. That is, among the five second finger plates 220, the leftmost or rightmost second finger plate 220 is not connected to a third finger plate 230. The finger-restricting component composed of the five first finger plates 210, the five second finger plates 220, and the four third finger plates 230 can be adapted to the left or right hand and the front or back of the palm.

[0044] In this embodiment, a support frame 800 is separately installed at the bottom of the fixing plate 100. An inner rod and an outer rod are formed in the middle of the support frame 800, sliding perpendicularly to each other. The outer rod is sleeved on the inner rod, and a fastening screw is threaded onto the outer rod, abutting against the inner rod. This allows the support frame 800 to have an adjustable height. At least four rollers 810 are provided at the bottom of the support frame 800, all of which have a braking function. The support frame 800 can raise and adjust the height of the fixing plate 100, facilitating treatment operations directly on the fixing plate 100. The rollers 810 facilitate the movement of the support frame 800.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
